From SOU Carolina Division Timetable No. 18, In Effect 12:01 A.M., March 16, 1980.
Comments regarding older usage welcome.


Notes

The SOU signals are shown with staggering, which does not yet appear here. Forms with 2 arms at "double distance" from each other, vertically, are also shown, but the color sequence from top to bottom is always identical with that of the corresponding 2-arm single-distance signal. There is one exception, Restricted Proceed, which has no 2-arm single-distance signal.

Limited triangles are shown acute angle to left.

High and dwarf signal aspects are shown in a table structure, very similarly to the style used here. The columns are labeled "High Signal" and "Dwarf Signal".
